HPHT Rough Diamonds​ Description

Lab grown diamonds can be made by HPHT(High Pressure and High Temperature) and CVD(Chemical Vapor Deposition) methods. The apperance of HTHP and CVD rough diamonds are different. CVD rough diamonds usually are flat plates.

The lab grown diamonds is divided into different levels and different uses. Industrial grade diamonds are widely used. However, the production difficulty of gem quality diamonds is very different from that of industrial grade diamonds.

In the past, gem quality lab grown diamonds contain many impurities, and they could even be adsorbed by iron absorption stone. It's very difficult for you to distinguish the gem quality lab created diamonds by using the iron absorption stone because of the improvement of the technology. With professional equipment, the comparison of the color, crystal shape and crystal surface characteristics, internal inclusion characteristics, absorption spectrum and ultraviolet fluorescence characteristics of the tested diamonds can "completely distinguish the artificially cultivated diamonds from the natural diamonds". After all, natural diamond crystals were formed billions of years ago, while artificially cultivated diamonds can only be formed in a few days.

Parameters of HPHT Rough Diamonds

HPHT Rough Diamonds​​ Introduction

​Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Rough Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Rough Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
